Status Pencemaran pada Sungai Belawan Provinsi Sumatera Utara

Abstract

River pollution occurs as a result of the entry of waste from various human activities without being supported by the capacity of the river itself. Increasing human activities, changes in land use and the increasingly diverse lifestyles of urban communities that produce domestic waste make the burden of pollution in rivers greater over time. The decline in water quality occurs as a result of uncontrolled waste disposal from development activities along the river so that it is not in accordance with the carrying capacity of the river. The river will receive input of materials or energy from areas along the river flow or all human activities related to waste production and then flow through river bodies. This research was conducted in June 2024. The research method used was purposive sampling. The overall research results are where the water quality status of the Belawan River spatially, North Sumatra Province based on the IP method in the lightly polluted category NSF-WQI in medium (moderate) - good status and based on the CCME method in the moderately polluted category - good with a comparison to the river water quality standards.
